Invalid content taglib

[Ekaterina Galkina]

Hi,

I'm trying to test <taglib> element in web.xml.
I'm placing

<taglib>
		<taglib-uri>http://myFunc/Functions</taglib-uri>
		<taglib-location>/WEB-INF/lib/Functions.tld</taglib-location>
</taglib>  

under <web-app> and getting the following error ("Eclipse Europa", "Java EE Preview at localhost" server):

Invalid content was found starting with element 'taglib'...

What's wrong have I done? Thank you for any hints.

Hi !

under <web-app> and getting the following error ("Eclipse Europa", "Java EE Preview at localhost" server):
Invalid content was found starting with element 'taglib'...

I don't see anything in those lines. I guess that you get that error when starting up the server?

Can you post your full web.xml and your full stacktrace?

Regards,
Frits

ok, here is the full web.xml.

yes, the error occures when I'm starting up the server. (But before that Eclipse displays it too like compile errors)

If you are using Eclipse, try formatting the web.xml with CNTRL-SHIFT-F and see if the problem goes away. It seems there are characters that the parser cannot handle.

Your web.xml looks ok, apart from the formatting.

is it possible that Java EE preview server doesn't support taglib tag? May be I should use Tomcat or other server...
Without taglib tag everything is ok.
yes, I'm using Eclipse Europa and build-in web-server Java EE preview. CNTRL-SHIFT-F didn't help.

hmm, I guess that it supports EE5 and Servlet 2.4, and then it should be able to read the taglib tag.

It seems it doesn't like the "http://" string, try this:
<taglib> <taglib-uri>Functions</taglib-uri> <taglib-location>/WEB-INF/lib/Functions.tld</taglib-location> </taglib>
and use
<%@ taglib prefix="func" uri="Functions"%>
in your JSP.

I don't know why, but after I changed web-server the problem has been solved.
